Chopper Stabilization Technique
Chopper Stabilization is an innovative circuit technique that is
used to minimize the offset voltage of a Hall element and an asso-
ciated on-chip amplifier. Allegro patented a Chopper Stabiliza-
tion technique that nearly eliminates Hall IC output drift induced
by temperature or package stress effects.
This offset reduction technique is based on a signal modulation-
demodulation process. Modulation is used to separate the unde-
sired DC offset signal from the magnetically induced signal in the
frequency domain. Then, using a low-pass filter, the modulated
DC offset is suppressed while the magnetically induced signal
passes through the filter. The anti-aliasing filter prevents aliasing
from happening in applications with high frequency signal com-

ponents which are beyond the user’s frequency range of interest.
As a result of this chopper stabilization approach, the output
voltage from the Hall IC is desensitized to the effects of tempera-
ture and mechanical stress. This technique produces devices that
have an extremely stable Electrical Offset Voltage, are immune to
thermal stress, and have precise recoverability after temperature
cycling.
This technique is made possible through the use of a BiCMOS
process that allows the use of low-offset and low-noise amplifiers
in combination with high-density logic integration and sample
and hold circuits.
